the game runs sli and crossfire, the problem is everyone is having better results running one card.
for example, im running dual 5870s and heres whats up with me:
all settings on max pretty much
single card average: 24-28 fps (GPU 98%)
dual card average: 18-22 fps (GPU 73% each)
the game actually plays nice for me on one card, but the thing that annoys me is i know im nerfed.. i should be able to run this game at a solid 30 fps.
ive been told nvidia users are having the same issues but i dont use it so im not sure.
SE needs to fix this issue for high end users!
